The jaws that are in this shark are truly remarkable as they consist of three rows of teeth. When the shark damages or breaks a tooth there is already another tooth ready to cycle back into this place. When it goes in to take the intended prey the lower jaw drops as the upper jaw protrudes forward. The teeth in the lower jaw hold the prey in place as the upper jaw slams shut tearing up to 15kg of flesh in a single bite. They can also consume over 200kg of food in one feeding session.
The signature bite of the Great White is made possible by the fact that unlike humans the upper jaw is not fused. The jaw freely moves just below the brain casing powered by an enormous muscle structure. Having double-edged serrated teeth combined with a power bite of more than 340kg easily explains how this formidable mouth can inflict so much damage.
